Comparison of Precision Gear Reducers Made of Various Materials
The precision gear reducer's bearing capacity is primarily governed by the geometric model size characteristics of the gear and the gear material (the type of material and the heat treatment production process). Building materials often used in manufacturing and gearing include ductile iron, high-quality carbon steel, and alloy steel, among others. Normalizing, quenching and tempering, surface quenching, carburizing quenching, and nitriding are the most common heat treatment process study topics.
According to the tooth surface hardness requirements, the precision gear reducer system is typically divided into soft tooth surface (the effect of tooth surface hardness is generally less than 300HBW), medium hard tooth surface (generally 300-350HBW in terms of tooth surface hardness), and hard tooth surface (tooth surface hardness is generally 300-350HBW). The surface hardness is clearly larger than 350HBW) three data kinds, and the difference in carrying innovation capacity and pricing is not significant (when the geometrical feature size of the gear is the same).
Among them, the alloy steel carburizing and quenching hard tooth surface gear (tooth surface hardness is 58-62HRC) is one of the major horizontal direction challenges of our gear reducer technology. The basic dimensions and quality standards of the gear structure are better than those of the soft tooth surface (normalizing, quenching, and tempering) between the carburized and quenched gears due to the good strength against tooth surface fatigue (pitting, spalling) and the high bending movement strength of the tooth root.
Because the gear is tiny, the size and quality of the housing are also lowered (but the size and quality of the bearing are not reduced). Despite the fact that gear work without carburizing and quenching often requires more expensive materials (generally alloy steel), somewhat high-cost hardening treatment techniques and processing methods (such as gear grinding, etc.), owing to the aforementioned sequence of benefits, It is currently frequently employed in newly built replacement precision gear reducer optimization products.
The following are the basic parameters of the reducer design:
The nominal maximum torque T1 = 21400N m, the speed n1 = 500r/min, the transmission ratio I = 3, the use correlation coefficient KA = 1.25, the minimum system safety risk factor for pitting corrosion SHmin = 1.3, and the minimum degree of bending information security management are used in the pinion. SFmin=2.3 as a coefficient. The material product grades and prices in the table differ from the circumstances, but the items compared, such as center distance, structural design size, bearing mass (weight), total mass (weight), and so on, are comparable. For those who can pick the machine, there is a decent reference value.
